Interplay of the two ancient metabolites auxin and MEcPP regulates adaptive growth. [PDF]
, 2018 The ancient morphoregulatory hormone auxin dynamically realigns dedicated cellular processes that shape plant growth under prevailing environmental conditions. However, the nature of the stress-responsive signal altering auxin homeostasis remains elusive.

phot1 inhibition of ABCB19 primes lateral auxin fluxes in the shoot apex required for phototropism [PDF]
, 2011 It is well accepted that lateral redistribution of the phytohormone auxin underlies the bending of plant organs towards light. In monocots, photoreception occurs at the shoot tip above the region of differential growth.

Temporal and spatial auxin responsive networks in maize primary roots
Quantitative Plant Biology, 2022 Auxin is a key regulator of root morphogenesis across angiosperms. To better understand auxin-regulated networks underlying maize root development, we have characterized auxin-responsive transcription across two time points (30 and 120 min) and four ...

The Arabidopsis Book, 2014 lndole-3-acetic acid (IAA), the most important natural auxin in plants, is mainly synthesized from the amino acid tryptophan (Trp). Recent genetic and biochemical studies in Arabidopsis have unambiguously established the first complete Trp-dependent auxin biosynthesis pathway.

New Phytologist, 2020 Summary The gaseous plant hormone ethylene induces the ripening of climacteric fruit, including apple (Malus domestica). Another phytohormone, auxin, is known to promote ethylene production in many horticultural crops, but the regulatory mechanism ...

The cyclophilin A DIAGEOTROPICA gene affects auxin transport in both root and shoot to control lateral root formation [PDF]
, 2015 Cyclophilin A is a conserved peptidyl-prolyl cis-trans isomerase (PPIase) best known as the cellular receptor of the immunosuppressant cyclosporine A. Despite significant effort, evidence of developmental functions of cyclophilin A in non-plant systems ...

Up in the air: Untethered Factors of Auxin Response [version 1; referees: 5 approved]
F1000Research, 2016 As a prominent regulator of plant growth and development, the hormone auxin plays an essential role in controlling cell division and expansion. Auxin-responsive gene transcription is mediated through the TRANSPORT INHIBITOR RESPONSE1/AUXIN SIGNALING F ...

Auxin Response Factors: output control in auxin biology [PDF]
Journal of Experimental Botany, 2017 AbstractThe phytohormone auxin is involved in almost all developmental processes in land plants. Most, if not all, of these processes are mediated by changes in gene expression. Auxin acts on gene expression through a short nuclear pathway that converges upon the activation of a family of DNA-binding transcription factors. These AUXIN RESPONSE FACTORS (

The PIN-FORMED (PIN) protein family of auxin transporters [PDF]
, 2009 The PIN-FORMED (PIN) proteins are secondary transporters acting in the efflux of the plant signal molecule auxin from cells. They are asymmetrically localized within cells and their polarity determines the directionality of intercellular auxin flow.
